What would Alicia think in the chair !?

Diane and Alicia looked at each other at the last scene of The Good Wife S06E06.

What makes she smile!? Was she thinking of Will!? Or Does her smile reflect confused feelings; life unexpected which turned out to be her sitting in Dead Will’s desk. 

Apparently, she accepts her feelings of Will’s presence even though he’s not there any more. Diane also feels that by looking at her.

I’m excited to watch more of Alicia. I don’t mean her changing looks and attitudes toward the world but want to see her mature enough to face the harshness of the reality.
